In an analysis of wild-type H. pylori strain J99, all the genes listed in this table had pH 5/pH 7 expression ratios >2 SDs higher or lower than the mean pH 5/pH 7 ratio of all arrayed genes. In contrast, in an analysis of strain J99-165Km or J99-1364Km, the genes listed in this table were not acid responsive.
References in parentheses indicate acid-regulated genes identified by Bury-Mone et al. (8), Merrell et al. (24), or Wen et al. (40).
An index value was calculated for each gene by dividing the pH 5/pH 7 expression ratio for the wild-type strain by the pH 5/pH 7 ratio for the indicated mutant strain.
